The UK's highest earners live in Wandsworth, Westminster, and Richmond upon Thames - all in London.

The weekly wage of the average worker in those areas was £660.90, £655.70 and £655 respectively in April 2014.

At the other end of the spectrum, the average weekly earnings of someone in West Somerset were just £287.30.

The ONS prefers to use the median as its measure of average earnings “as it is less affected by a relatively small number of very high earners and the skewed distribution of earnings”.

All the data in the report - the Annual Survey of Hours and Earnings (ASHE) - were taken from a 1pc sample of jobs in the HM Revenue and Customs’ Pay As You Earn (PAYE) records. Self-employed workers were not included.
